William Mortimer

William Mortimer (1280-February 1337), also known as William de la Zouche, was a noble of the Kingdom of England.

Biography
Mortimer was born in 1280, and he became the first baron of the House of Mortimer. He was loyal to Isabella of France and Roger Mortimer during their 1326 invasion of England, and William besieged Caerphilly Castle in 1327 when Earl Hugh of Winchester's eldest son (also named Hugh, not to be confused with his younger brother Hugh Despenser) fought the new regime. In January 1329 he eloped with Eleanor de Clare, the widow of Hugh Despenser the Younger, and King Edward III of England ordered for them to be arrested. They were both released after Eleanor paid a large sum of money to the king, and Mortimer and Eleanor both died in 1337.
